my project is a wireless keyboard. can you help me with what microcontroller to use? and also if it's better to use bluetooth or zigbee to send data wirelessly. power consumption is very crucial which means the lower the power consumption, the better. thanks in advance

EDIT: i mistakenly clicked on the "Mark as solved" button, sorry.

Bluetooth consumes more power and may be a cause of worry during continuous operation for hours to gether.. So in terms of power consumption i would prefer zigbee to to more suitable over bluetooth....
you could use any controller in that matter for your project
 

thanks. how do i configure the zigbee,what specific zigbee to use? this is just my first encounter of zigbee, i don't know how it works.
 

you could use a self contained Zigbee device and communicate with it via a serial line, e.g. XBee
XBee-PRO® 802.15.4 OEM RF Modules - Digi International

you could use a Zigbee stack supplied by a microcontroller manufacturer, e.g. the Microchip Zigbee stack

these days I often use MiWi which is a simpler protocol than Zigbee

to save power you can supply the wireless device via a MOS FET which allows the microcontroller to switch off the device off when it is not being used

how do i connect the controller to the zigbee modules that you posted? thanks
 

using an XBee you can connect it to the UART Tx and Rx lines and send commands to it to control the device
for Microchip's Zigbee have a look at the application notes on their web site

okay.thanks.another question, is RF transceiver better? in terms of power consumption. also, is it harder to implement using it?

xbee is less power consumption compared to rf transceivers.... and its not hard to implement....

i don't know what specific zigbee to use. and the zigbee modules that i find cost a lot.

the power consumption is still more than zigbee modules if it is run on a battery the power parameter will be a problem in RF...

the problem i have with zigbee is that i can't find a low cost one. and i don't know how to use zigbee.what do you suggest. Thanks in advance
 

Zigbee is complex and the modules do tend to be expensive (one reason why we gave up using it).
Have a look at Microchip's MiWi which is a simpler alternative using similar protocols

if this is the case sir, is it better to use RF or Bluetooth than zigbee since low power consumption and low cost are considerations?
 

I dont know to whom you are asking about the solution .,,,,,,,,,,,, but it depends on your B.O.M and cost. Both low power and lost cost cannot be easily achieved... if you need both then go for RF transceiver IC by microchip..........

Thanks sir.the problem with rfPIC12F675K is that it doesn't have the receiver capability. it's a dedicated transmitter. i don't know what to use as a receiver for this.
